Mad Monster Mansion is the seventh world in Banjo-Kazooie. It is a haunted mansion that features a maze, a pond with a fountain and a very large well. There is also a church in the vicinity. It is implied, though never stated outright, that it belongs to Gruntilda. Motzand, Napper, Loggo and Tumblar appear here. Mumbo Jumbo turns Banjo into a pumpkin.
